Problems solved by technology

The excavator of the drum-type potato harvester operates in sticky soil, and the sticky soil will adhere to the surface of the cutter and the installation structure of the cutter, causing the cutting force of the cutter to decrease and the cutting resistance to increase, and the harvesting power to increase, which hinders tuber crops such as potatoes Entering the subsequent separation and screening device, the operating efficiency is reduced

Embodiment Construction

[0021] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0022] A two-stage drum potato harvester drum, such as Figure 1-5 As shown, it includes an outer roller, an inner roller and a differential device 7. The outer roller includes an outer roller installation shaft 1, an outer roller filter frame 2, an outer roller filter 3, an outer roller connecting ring 6, an outer roller Roller cutter annular mounting bracket 8, outer roller annular cutter 9;

[0023] The inner drum includes an inner drum filter screen 12, an inner drum installation shaft 13, an inner drum cutter mounting ring bracket 14, an inner drum ring cutter 15, and an inner drum filter screen frame 16;

[0024] The outer drum filter screen 3 is fixedly sleeved on the outer drum filter screen frame 2, the front end of the outer drum filter screen frame 2 is fixedly connected to the outer drum connecting ring 6, and the axis of the outer ...

Abstract

The invention relates to a two-stage roller potato harvester roller which comprises an outer stage roller, an inner stage roller and a differential gear. The outer stage roller comprises an outer roller installation shaft, an outer roller filter net frame, an outer roller filter net, an outer roller connecting ring, an outer roller tool annular installation support and an outer roller annular tool. The outer roller and the inner roller are in differential connection; due to the fact that the internal annular excavation tool in the inner roller is of low-speed excavation, the mechanical damage caused by the tool to tubers is lowered, the outer annular excavation tool of the outer roller is of high-speed excavation, the harvester excavating efficiency is improved, the internal annular excavation tool and the external annular excavation tool are differential, the certain soil shear effect between the tools is achieved, and the certain tool self-cleaning capability is achieved.

Description

technical field [0001] The invention relates to the technical field of potato harvesting, in particular to a two-stage drum potato harvester drum. Background technique [0002] At present, large-scale potato harvesting in developed countries and Northeast my country mostly uses high-power self-propelled combine harvesters, which can complete operations such as vine cutting, digging, soil and potato separation, size grading, bagging, and transportation at one time. Its power consumption is high, and it is not suitable for small and medium-sized land plots with many mountains, large slopes, and small planting areas in my country. [0003] Potato harvesting equipment currently used in mountainous and hilly areas in my country generally uses digging shovels to cut the soil at a certain angle, digs out the soil and potato shovels and transports them to the swinging separation screen, and achieves the effect of separating potatoes from soil under the action of vibration and frictio...
